Acute Kidney Injury
Conditions
Brief summary
This prospective cohort study aims to explore the susceptibility to acute kidney injury after heart surgery in SMN1+/- genotype population. This study also aims to analysis the effect of SMN1+/- genotype on postoperative AKI and the development of chronic kidney disease, as well as dose-compensating effect of different copy number of SMN2 gene on SMN1 +/- genotype.
Detailed description
This prospective cohort study aims to explore the susceptibility to acute kidney injury after heart surgery in SMN1+/- genotype population. Real-time PCR is used to detect copy number variations in the peripheral blood SMN gene on 1206 patients with heart surgery. This study also aims to analysis the effect of SMN1+/- genotype on postoperative AKI and the development of chronic kidney disease, as well as dose-compensating effect of different copy number of SMN2 gene on SMN1 +/- genotype.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of participants with occurrence of acute kidney injury (AKI) after cardiac surgery | 48 hours | The definition of the occurrence of acute kidney injury is according to the acute kidney injury (AKI) definition and staging criteria released by Kidney Disease: Improving Global Outcomes (KDIGO) in the year 2012 |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Number of participants with occurrence of acute kidney disease (AKD) after cardiac surgery | 3 months | The definition of the occurrence of acute kidney disease is according to the acute kidney disease (AKD) definition criteria released by Kidney Disease: Improving Global Outcomes (KDIGO) in the year 2012 |
| Glomerular Filtration Rate(GFR) | 90 days | Glomerular filtration rate (GFR) is defined as the volume of plasma that is filtered by the glomeruli per unit of time, and is usually measured by estimating the rate of clearance of a substance from the plasma. |
